IMPROVEMENT IN EEEDINe-MEGHANISM ros Genome-ENGINES.

TQ WHOM ITv MAY CONGERN:

.Be it known that I, THOMAS SAMPsoN, of 'Wanskuch in the county of Providence, State of Rhode Island, haveinvented certainnew and useful Improvements in Machines for Preparing Fibrous Substances for Spinning; and-I hereby declare the following to be a full, clear, and `exact description ofthe same, referencebeing had to vthe accompanying drawing, which represents, in perspective, that portion 'of a card-feeding`machine to which my improvements are applied.

` My invention relates to a machine in general usefor feeding cards, for which Letters Patent of the United States, No. 18,888, weregranted to James Apperlyfan'd W. Clissold.V This machine is generally attached to the second breaker and inisher-cards. AItsact-ion is too well known to need description, thc feed being produced by means of a travelling-guide, which lays 'thesliver diagonally in continuons 'rows upon an endless\apron, which carries itto the cards. Y A l The object ofthis. .sellactingfeeder" is to produce a more perfect and even distribution of' the material,

' and' a more uniform sliver than could be eieeted bythe useofordinar'y feed-mechanism. But it has, however,

been found, b'y experience, that, when'certain kinds of stock are used, thepassage of the sliver,as it enters the machine, over the stationary bar or shaft, in front of the feeder, causes a; friction which tends to stretch the sliver between the cards, nud consequently to produce uneven work. l I

The object of myinvention Ais to obviate this diicnlty, and, to this end, lt consists ofthe combination, with the feed-mechanism `of a revolving slaat-amounted in the front-'df the machine, and' actuated 'so as to travel at about the same'rateoffspeed as the sliver, which passes over it to the feed or traversing-rolls. As the shaft thus moves with the sliver, insteadof remaining stationary, there is no friction produced, andl consequently the -stretching of fthe sliver before mentionedis prevented.v i v v My invention'will lie-readily'comprehended' byreference tothe accompanying drawi'ngsfin which only so much of the machine is Vrepresented as i's necessary to illustrate the same.

' The sliver, in. its progress to the vtravelling-'guide a of the feeder, passes over a shaft, b, in `frontof the. frame. Thisshaft has been heretofore made stationary, thus giving vrise to the evils `above'mentioned. To obviate such evils, Imount 'the shaftin bearings c c, formed in the frame in such manner that it isgrendered capable of revolving. The power for actuating the shaft can be taken from any part'cf the working-gear. As above said, theshaft should travel at aboutthe same rate of speed vasV the sliver which passes over it,v and, in order to communicate this inotion, I connect it with the' pulleyld, mounted upon the s haft'm, whichcarries the gear for effecting Ythe movement of the endless' band, which carries the pin by which the traversing-guide is moved to and fro. The conugction is made by means of an" endless band, which passes irom the pulley d, over the smaller pulleyf, mounted 'on' the end of thesbaft-b. These wheels or pulleys bear su ch relation insize to each other, that the rate of speed atw'hich the shal't revolves is; about the same as that at which the traversing` Vguide-moves. It is needless to sayJ however, that this movement maybe communicated to the roll from any other part of the driving or motor-mechanism, and by any suitable means..A Y

Having now described my invention, and the manner in which the same is or may be carried into eifect, what I.claim,.and desire to'se'cure by Letters Patent, is v y A In a machine such as described, the application` and use of a revolving shaft, mounted in the' front of the machine, at or near the point where. the sliver is delivered to the traversing-guide, substantially as and forv the purposes herein shown and ser, forth. Y

In testimony whereof, I iave signed my nameto this speciicationbefore two subscribing witnesses.
